Scandere vs yale 11.7

I'm planning on buying a new rope in the next few days. I climb almost all srt on a bull dog bone. I only have one rope that works well with it which is km3 max, but I would like something a little larger in diameter to help my aging hands grip. As the thread title says, I'm looking at Yale 11.7 ( blue moon, poison ivy, ect) or the scandere, also 11.7mm. I like the stiffness of the km3 max, it works great in the bdb, just a little hard to grip. I have some imori (12mm) which kind of binds up in the bdb, I think due to its softness not because of diameter. So does anyone have experience with both of the ropes I'm looking at? How does the blue moon/ poison ivy do in a bdb? Is the scandere hard to grip? Thanks for any insight.
 
I've got the adjustable bone and prefer km3 max as well. I've used mine on scandere and even with out adjustment it runs pretty good. Seems like it'd be excellent with some tweaking. The jacket is very similar to the max and the diameter feels thicker in the hand.
 
Thanks to all of you for the input. I am leaning hard towards the scandere. I've seen a couple people say it's a bit bouncy. Looking at elongation under load data from manufacturers is a little perplexing. Km3 max 11 mm is listed as 1% elongation from 50 - 150 kg. Does that mean if you preload it with 50kg then add 100 more kg it stretches 1%? Scandere is 3% at 10% of breaking weight ( 10% is 322 kg). Yale gives a chart and it looks like at 5% (161 kg) scandere is at 1.5% and at 2.5 %(80.5 kg) it's at roughly .75% of stretch. It's hard to read the bottom of that chart. Does that mean it has less than 1% of stretch between 50 and 150 kg ?
 
I probably am overcomplicating it. I live in Pennsylvania, we don't have 200 ft tall trees around here. It's pretty rare I'm tied in higher than 75 ft, 90 ft Max. If I'm tied in that high in an oak or Sycamore around here, there's usually more Flex in the branches than in the Rope. I seriously doubt I would notice a small difference in elongation. It would just be nice if the different rope companies worked off the same standard so we could easily compare when we can't get our hands on the actual rope before we buy it.

Get the xstatic, works treemendously with cbdb

I'm new to climbing and I don't have a lot of experience with various ropes, only a few. I would love to buy a rope that you suggest that has less stretch. I'll buy 70' of a 11.4-12.7mm rope if you suggest it.

I'd like to see what I'm missing. I've been looking for an excuse to buy some Samson rope anyway way.

Whoops. I just looked at xstatic. I ain't buying that rope for nothin. Too fugly.

Both rope manufacturers list Blue Moon and Xstatic at 1.4% elongation.

Scandere is listed at 3%.

I've been climbing for about 16 years, but I just started with srt and mechanical devices a few months ago. Before that I was all drt or Ddrt or is it mrt? What ever it's called when you climb on a loop that you adjust length with a friction hitch. So I'm new to ropes that work well with srt, but I can say this with a fair amount of confidence, if you only have 70 feet of rope in your srt system, stretch will be of little concern. If your base tied with a 75 foot TIP your going to have at least 150 in your system. 3% of 150 is 4.5 feet of stretch 3% of 70 is 2.2 feet. But the 3% rating for scandere is at 10% of breaking strength. If you get a 710 lb load on your rope while ascending, I would be surprised. I think that is why teufelberger rates there ropes by the 50 - 150 kg measure. I think that would be a fair approximation of the change in load a rope would see between steps or thrusts or pulls during accent.

Wespur is publishing all the numbers as being at 10% abs, but the teufelberger web site lists the same percentages as being from 50-150 kg which is 50% or less of 10% abs. Maybe I don't understand some aspect of this, but it seems like wespur might be wrong.
 
If you want Samson and don't want stretch, try Samson Static. Comes in a variety of diameters. In 11mm, has a hard hand (likes ABs no problem, and dress and set well with long trails for others), but static as fk. Everything else I've used srt since seems bouncy. This rope doesn't get much fan fair, but it's seriously static and good for srt in my opinion. It used to be on the Wesspur tables, but I haven't looked in a while.
